Kinetis is the most scalable portfolio of low power, mixed-signal ARM®Cortex™-M4 MCUs in the industry. Phase 1 of the portfolio consists of five MCU families with over 200 pin-,peripheral- and software-compatible devices. Each family offers excellent performance, memory and feature scalability with common peripherals, memory maps, and packages providing easy migration both within and between families.

Kinetis MCUs are built from Freescale’s innovative 90nm Thin Film Storage (TFS) flash technology with unique FlexMemory (configurable embedded EEPROM). Kinetis MCU families combine the latest low-power innovations and high performance, high precision mixed-signal capability with a broad range of connectivity, human-machine interface, and safety & security peripherals. Kinetis MCUs are supported by a market-leading enablement bundle from Freescale and numerous ARM 3rd party ecosystem partners.

MCBTWRK60评估板技术指标:

The MCBTWRK60 is designed to be a very flexible evaluation board for the Freescale Kinetis family of microprocessors. The MCBTWRK60 evaluation board can be expanded to build hardware prototypes.

The Freescale Kinetis K60 microcontroller (U1) provided with the MCBTWRK60 board is a high-end MK60N512VMD100 device with advanced capabilities.

A 50.0 MHz oscillator (Y1) provides the clock signal for the CPU when a jumper is installed on pins 1-2 of jumper J6. Moving the jumper to pins 2-3 allows external clocking from another board via the Primary Elevator.
